Applying the second method to the configuration given below, a sinus with –9.0 dBm is fed into
remote equipment. Calculating the expected output level at local equipment with the formula above
results to:
L
= -9.0 dBm – (-4.00 dBr) + (-1.00 dBr)

B.10.11
Teleoperation port AF1
If the port AF1 is not used for a telephony application and if the port is switched to 'On –
disconnectable' or 'On – non disconnectable', take the measurement as described in B.10.10.
B.10.12
Teleoperation port AF2
If the port is switched to 'On – disconnectable' or 'On – non disconnectable' take the
measurement as described in B.10.10.
B.10.13
Teleoperation port AF3
If the port is switched to 'On – disconnectable' or 'On – non disconnectable' take the
measurement as described in B.10.10.
B.10.14
Teleoperation port AF4
If the port is switched to 'On – disconnectable' or 'On – non disconnectable' take the
measurement as described in B.10.10.
B.10.15
Teleoperation AF4 used for ext. Teleprotection
After measurement of B.10.14 is done:
1.
Recalculate expected output level of AF4-OUT by adding the NSD570 boost value,
available in the configuration view (View / Display Configuration / Effective boost
value ext. TPE1/2/3).
2.
Activate the EXT-BOOST input at the remote equipment. If EXT-BOOST is configured as
'inverted', contacts at terminal, teleoperation, 9a-9b must be opened, otherwise closed.
3.
Take the measurement at AF4-OUT of local equipment.
